The Supeffund Chemical Data Matrix (SCDM) is a database containing the Hazard Ranking System (HRS) factor and benchmark values for 422 hazardous substances commonly found at sites evaluated using the HRS. The HRS is a mathematical evaluation system used to determine the relative risk posed by a hazardous waste site based on factors reflecting the likelihood of a hazardous release. Additionally, the database includes physical, chemical, and radiological data used to calculate HRS factor values. The HRS assigns extra weight to factor values for sites where people and sensitive environments are exposed to hazardous substances at or above the benchmark values.
